In the past I've noted that people were having fun with their numeric keypads and function keys that seemed to depend on what environment they were running TinTin++ in. Well I found this item by the current author of "xterm" which shows some useful information about emulating VT220 terminals and how well some emulators do (or don't) achieve it.

I was thinking of adding a poll to this post to see what terminals people are using for TinTin++ (including inside a cygwin environment on a WinTel PC). Then I started to research the choices available and barfed on the wide range that came up!

Perhaps people could append here any terminals that they USE for it that earlier posters have NOT mentioned.

This does touch upon "Some questions about your Terminal Emulator" that Scandum asked in the Announcement area of the Forum but looking into it the behaviour that was being looked at there could depend heavily on the terminal type selected and various configuration options...
